Application led August 6, 1920. Serial No. 401,686.

T all whom t may concern Be it known that I, DUDLEY B. CLARK, a citizen of the United States, residing at the village of Beinus Point, in the county of Chautauqua and State of New York, have invented certain new and useful lmprovements in Cigar-Lighters, of which the following, taken in connection with the accompanying drawings, is a specification.

Thel invention relates to electric lighters or igniters, the special use being shown as a tobacco lighter; and the object of the improvenient is, first, to provide two resistances which are placed in series and connected to an electric circuit of commercial standard voltage; the first resistance is the lighting or igniting element which is provided with ventilation through said cabinet, so that when a cigar is placed against said lighting or igniting element and drawn upon, a light will be produced, and the second resistance is the series element; and the invention consists in the novel features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is a perspective view 4of the cigar or tobacco lighter, showing the lighter head with its ventilating cap. Fig. 2 is a. vertical diametral sectional view of the cigar or tobacco lighter at line 2-2 in Fig. 3 showing the preferred construction and arrangement of the parts; and Fig. 3 is a sectional View of the cigar and tobacco lighter at line 3 3 in Fig. 2 showing the ventilation through the rear of the lighter case. Fig. 4: is a plan view of the lighter head, a portio-n of the rim cap being broken away to show the construction of the same, and the wire lighting element threaded through the insulating block in spiral arrangement; and Fig. 5 shows said spiral arrangement andthe connections thereto; and Fig. 6 is a plan view of the insulation with the holes in circular arrangement therein ready to receive the wire resistance lighting element which is sewed through said holes. Fig. 7 is a sectional view of the insulation blocks showing the manner in which the lighting element is connected through said blocks and the second resistance element to the source of supply for electricity. Figs. 8 and 9 show the heat and electric iiisulation blocks as provided on the lighten head; and Fig. 10 shows the spaced insulation sleeves which separate said blocks; and Fig. '11 is a perspective view of the neck support for the lightervhead which is turned slightly to one side in order to provide a convenient angle of approach to the lighting element. Fig. 12 shows a slight modification of the wire lighting or igniting element in which the said element is arranged in the form of a concentric sunken coil oii the face of the heat and electric insulation block; and Fig. 13 is a sectional view at line 13-18 in Fig. 12 showing the preferred construction and arrangement of said modification. F ig. 141 is a plan view of the under side of the block as shown in Figs. 12 and 13, showing the manner of connecting the coils of the wire lighting or igniting element.

Like characters of reference refer to corresponding parts in the several views.

lhe numeral 15 designates the casing which is preferably made of sheet metal. rThe neck portion 1G is preferably a Monel metal tubular casting which is flanged around the base and attached by suitable bolts 17 to the top of the casing 15, and has its upper end turned slightly at an incline to receive the lighting head 18 thereon at said convenient angle of approach.

The lighting head 18 is composed of the electrical and heat insulation blocks 19 and 21 which are separated by the insulation sleeves 20 around the attaching screws. T he insulation block 21 is preferably molded from heat resisting material sulicientlv strong to attain the purpose. lThe sleeves or cylinders 2O around the attaching screws 22 and 26 are preferably made from a strong heat insulating material, and permit the air to surround the block 21. The screw bolts 2 2 extend through the blocks 19 and 21 and sleeves 2O into threaded holes in the neck portion 16, thereby firmly attaching the built-up lighting hea-d 18 upon the inclined face of the neck portion 16.

The insulation block 21 is a heat resisting or fire-proof electrical insulating composition block which has a central sunken portion or recess 23 on its outer surface, having the holes 211 therethrough, the wire resistance lighting element being sewn through said holes 24: and extending over the central portion of the surface of the sunken portion The wire lighting element 25 preferably consists of a resistance alloy, the ends of which are connected to the attaching bolts 26, which bolts 26 are connected in series by the wire 27 to the momentary push switch on the front of the casing 15 and to the series element or resistance 29 and thence to the cord 30. A second connecting wire 28 runs direct from the other connecting bolt 26 to said cord 30 and through said cord to a commercial lighting circuit or other source of electrical supply.

The insulation block 19 has the ventilating opening 38 therethrough for the purpose ot supplying air "from the interior of the casing l5 to the small openings or holes 24 in the block 2l through which the resistance wire lighting element 25 is sewn. rlhe wires 2T and 28 are preferably insulated with asbestos and when connected as described, the resistance of the lighting element and the series element 29 is so proportioned that said lighting element 25 will offer a greater resistance to the passage of the current than said series element 29 and will come to an incandescent heat more quickly than said series element- 29. By the time the lighting element 25 reaches said incandesent heat the series element 29 will havev heated suiliciently te increase its resistance and thus lower the voltage on 'the lighting element and act as an automatic check for the thermostatic control which tends to keep the lighting element from reaching excessive heat, yet when the switch is lirst closed, this arrangement allows the lighting element 25 to become ignited quickly, and then automatically checks a dangerous rise o1 temperature.

As thus arranged, when a cigar is placed against the lighting or igniting element 25 and dr wn upon, said hot wire lighting element as well the air heated by passing through the line holes 24 produce a heat which lights the cigar. The element 25 is protected from any possible mechanical injury by means of a perforated mica plate 3l which is securely held in place by the bolts 22. A rim cover 32 is provided which iits over the outer edge of the block 19 and is attached thereto by suitable screws, with the inner edge resting upon said mica plate 31, thereby aiding in holding it lirmly in position. The iigieriforations 33 in the mica plate 3l are preferably in the same general order as the holes 2li, so that the air draws through said mica plate 3l from about the resistance lighting element 25 thereby spreading 'the heat evenly over the diameter' of the recess 23 in the block 2l.

The lire-proof, heat resisting block 2l keeps the heat in the element 25 from heating back into the case 15. The round block 19 is prei'erably of hard asbestos material as stated, and supports the block 2O and 2O and rim 32. The heads of the bolts 26 are preferably placed in the recess 23 and covered bythe mica plate 31 so that there will be no danger of the edge of the rim 32 connecting with said bolt and thereby shortcircuiting the element Instead of the PLS resistance 29, a transformer might be used where an alternating current is available.

A modiiication of the lighting element is shown in Figs. 12 and 13 in which said lighting element is arranged as a spiral coil let which is sunlren in a spiral groove 35 over the small holes or perforations 24, in which arrangement the said wire resistance lighting element is not sewn through said holes 2l, but is merely arranged in a continuous coil in the spiral groove 35 as shown in F ig. l2. They may be used in concentric coils being connected in series on the under side ot the block and using the screws or screw bolts 22 as terminals, the same as the preferred forni of the lighting element. rlhe perforated inetal rim permits the escape oi the heat through the pertorations. lt carefully guards the lighting element and protects the head as against rough usage.

`4s hcreinbeliore described, when the 'liter is connected to an electrical source or supply by means of the wires 2T and 2S, all that is necessary is to place the end of the cigar against the mica plate 3- and draw the heat through the pertorations 33 therein, thereby quickly lighting the cigar end.

The casing or cabinet l5 has the ventinfli .a ac'- -1 rame openings oo in the reni. side and 39 1n the bottoni, which with the opening 37 into the neet: portion 1G and the ventilating openings 3S in the blocks 19 and 2O in combination with the minute perloi'ations 24C in blocks 2l and 33 in the mica plate 3l, permit e passage of the air through the caso and lighter head i8 to the end ol the r as it is pressed against the said mica The hot wire element threaded l.
